### What is the definition of a line segment?

A line segment is a straight path between two points that has a definite length but does not extend indefinitely in both directions. It is the shortest distance between those two points in a straight line.

### How would you prove that two triangles are congruent?

Two triangles can be proven congruent through the application of various methods such as the Side-Side-Side (SSS) postulate, Side-Angle-Side (SAS) postulate, Angle-Side-Angle (ASA) postulate, Angle-Angle-Side (AAS) postulate, and Hypotenuse-Leg (HL) theorem. If the corresponding sides and angles of two triangles are equal based on these postulates or theorem, then the triangles are considered congruent. This mathematical concept allows us to establish that the two triangles are essentially the same in shape and size.

### What are the properties of a parallelogram?

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Additionally, opposite angles are equal in measure, and consecutive angles are supplementary. The diagonals of a parallelogram bisect each other, meaning they intersect at their midpoints. Furthermore, the opposite sides of a parallelogram are congruent and the consecutive angles are supplementary, making it a shape with rotational symmetry of order 2.

### How do you calculate the area of a circle?

To calculate the area of a circle, you use the formula A = ?r^2, where A is the area, ? is a constant approximately equal to 3.14159, and r is the radius of the circle. Simply square the radius and then multiply by ? to find the area of the circle.

### Explain the concept of similar triangles.

Similar triangles are two or more triangles that have the same shape but possibly different sizes. This means that corresponding angles are congruent and corresponding sides are in proportion to each other. In other words, if you were to resize one triangle so that it matched the other, all the angles would remain the same. This concept is fundamental in geometry and trigonometry, playing a key role in solving for unknown side lengths or angles in geometric problems.

### What is the formula for finding the distance between two points in a coordinate plane?

The formula for finding the distance between two points (x1, y1) and (x2, y2) in a coordinate plane is given by the distance formula: ?((x2-x1)^2 + (y2-y1)^2).

### Describe the process of finding the volume of a rectangular prism.

To find the volume of a rectangular prism, you need to multiply its length by its width by its height. The formula for the volume of a rectangular prism is V = l x w x h, where V represents the volume, l is the length, w is the width, and h is the height of the prism. By multiplying these three dimensions together, you will determine the total amount of space the rectangular prism occupies in three-dimensional space.

### How do you calculate the surface area of a pyramid?

To calculate the surface area of a pyramid, you need to find the area of the base and the lateral faces. The formula for the surface area of a pyramid is SA = base area + (1/2) perimeter of base x slant height. Determine the area of the base first, then calculate the perimeter of the base and multiply it by the slant height of the pyramid divided by 2. Add these two values together to find the total surface area of the pyramid.

### Explain how to find the equation of a line given its slope and a point on the line.

To find the equation of a line given its slope (m) and a point (x?, y?) on the line, you can use the point-slope formula: y - y? = m(x - x?). Substitute the values of the slope (m) and the coordinates of the point (x?, y?) into the equation, and then simplify it to the slope-intercept form (y = mx + b) by solving for y. This will give you the equation of the line in the form y = mx + b, where m is the slope you were given and b is the y-intercept of the line.

### What is the Pythagorean Theorem and how is it used?

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be written as a² + b² = c², where c is the length of the hypotenuse, and a and b are the lengths of the other two sides. This theorem is used to find the length of a side in a right-angled triangle when the other two sides are known, which is commonly used in geometry and various real-world applications such as construction, engineering, and physics.
